  • Problem with non data bound value in ASP.NET DropDownList.

    - by ProfK
    I'm trying to 'inject' an [All Regions] item into my regions dropdown, as follows: <asp:DropDownList ID="regionList" runat="server" AutoPostBack="true" AppendDataBoundItems="true" Width="200px" DataSourceID="regionDataSource" DataTextField="Desc" DataValueField="RegionId"> <asp:ListItem Selected="True" Value="">[All Regions]</asp:ListItem> </asp:DropDownList> I also have a rank dropdown, for taxi ranks in a region, with the following select parameter: <asp:ControlParameter ControlID="regionList" Name="RegionId" PropertyName="SelectedValue" Type="Int32" DefaultValue="" ConvertEmptyStringToNull="true" /> So the expected behaviour is that when [All Regions] is selected, the ranks dropdown should get a null parameter, and mt SQL selects all ranks, for all regions. I know my SQL works with a null parameter, but the ranks dropdown is not data binding when I select [All Regions] on the region list. It binds when I select a region from the DB, but keeps that binding when I select [All Regions] again. What am I doing wrong?

  • How should a Gnome applet store its configuration data?

    - by George Edison
    I have a Gnome applet written in Python. In order to save configuration data/settings, it creates a file ~/.appname. However, this prevents multiple instances of the applet from being added to the panel because each cannot have its own settings. How can I store the settings in a way that allows each instance to have its own unique settings? Update: I specifically want to know how to store settings per instance.

  • SvcUtil and /dconly generates XSD's for data types NOT marked with the DataContract attribute.

    - by Bellerephon
    Has anyone ever encountered a problem with Svcutil and the /dconly option where it generates metadata for EVERY data type in an Assembly, even if it is NOT marked with with the [DataContract()] attribute? It also appears to be generating metadata for types only referenced in the code, such as XmlDictionaryReaderQuotas even though these are not a part of the physical assembly that I generated metadata on. Some info: Using the .NET 4.0 version of SvcUtil. Does not matter if class is empty or not. No references are specified in the command line for SvcUtil. Command line: "C:\In Progress Work (Prospective)\Prospective Server\Prospective Server\Management\Prospective.Server.Server.NET40.Debug.AnyCPU.dll" /nologo /t:metadata /d:"C:\In Progress Work (Prospective)\Prospective Server\Prospective Server\Management" /dconly

  • What time/date do you stamp your deployed data/exe files when they appear on the target system?

    - by Brian Frost
    It seems a good and clean thing to ensure that your deployed files appear on the target system with a consistent time/date. Many Applications seem to do this but other than for care of overwriting Users' existing data I guess it has no real significance. I'm having a purge on my installer packaging and I'd like to know if there any good reasons for specific date/time handling.

  • Castle Windsor Weak Typed Factory

    - by JeffN825
    In a very very limited number of scenarios, I need to go from an unknown Type (at compile time) to an instance of the object registered for that type. For the most part, I use typed factories and I know the type I want to resolve at compile time...so I inject a Func<IMyType> into a constructor ...but in these limited number of scenarios, in order to avoid a direct call to the container (and thus having to reference Windsor from the library, which is an anti-pattern I'd like to avoid), I need to inject a Func<Type,object>...which I want to internally container.Resolve(type) for the Type parameter of the Func. Does anyone have some suggestions on the easiest/most straightforward way of setting this up? I tried the following, but with this setup, I end up bypassing the regular TypedFactoryFacility altogether which is definitely not what I want: Kernel.Register(Component.For(typeof (Func<Type, object>)).LifeStyle.Singleton.UsingFactoryMethod( (kernel, componentModel, creationContext) => kernel.Resolve(/* not sure what to put here... */))); Thanks in advance for any assistance.

    I have a Drupal-6 module that needs the following mod-rewrite rule added to the .htaccess file of the site's root directory in order to work.

Can I use custom_url_rewrite_inbound(&$result, $path, $path_language) to do this? If so, could you please show me an example? Thanks, D

  • How to obtain JNDI data source for JPA/JTA DAO integration test?

    - by HDave
    I have a JPA application that has specified JTA transactions in persistence.xml. For whatever reason, I have found that when using JTA, you MUST specify a JNDI data source within persistence.xml as well. This is fine, unless you are trying to go integration testing outside a container and JNDI is not available. My questions are: a) is there anyway to inject a jdbc datasource into my JTA transaction manager? b) if not, how do a handle a JNDI lookup during integration testing?

  • Custom Output => List of Errors interpretation in VS2008 IDE.

    - by Hamish Grubijan
    Hello, I have a "database solution" project in VS2008 - it generates SQL for more than one DB vendor from some sort of templates. In order to save time, I also have a tool in VS2008 configured (a Python script), which can compile an individual stored procedure. Now, with the Python script I have the freedom of processing the output and have it take on whatever form I want. I am toying with an idea of having these errors and warnings somehow recognized and populating the click-able Error / Warning list. This is what a typical Oracle error looks like: LINE/COL ERROR -------- ----------------------------------------------------------------- 324/5 PL/SQL: Statement ignored 324/82 PLS-00363: expression 'VSOURCE_SYSTEM_ID' cannot be used as an assignment target Warning: Procedure created with compilation errors. PROCEDURE: ADD_PROPOSED error on creation Errors for PROCEDURE ADD_PROPOSED: LINE/COL ERROR This might be a long shot, but it is worthwhile for me. I do this stuff a lot. Thank you!

  • How to Automatically Refresh Data on Page Using Ajax on an Interval?

    - by Karnak
    I would like to load an XML file every 30 seconds and display its contents inside an HTML page. So far I know how to load the file, but I don't know how to automatically refresh it and display its updated contents. It would also be great if it did some error checking and if it displayed error.png image when it's not able to load data.xml file. Here is my code: <head> <script> window.XMLHttpRequest { xmlhttp = new XMLHttpRequest(); } xmlhttp.open("GET", "data.xml", false); xmlhttp.send(); loadXMLDoc = xmlhttp.responseXML; f = loadXMLDoc.getElementsByTagName("foo") function buildBar(i) { qux = (f[i].getElementsByTagName("qux")[0].childNodes[0].nodeValue); document.getElementById("displayBar").innerHTML = qux; } </script> </head> <body> <script> document.write("<ul>"); for (var i = 0; i < f.length; i++) { document.write("<li onclick='buildBar(" + i + ")'>"); document.write(f[i].getElementsByTagName("bar")[0].childNodes[0].nodeValue); document.write("</li>"); } document.write("</ul>"); </script> <div id="displayBar"> </div> </body> After searching the internet for a few hours I found many examples on how to do this, but I didn't know how to implement it in my particular case. I am not a programmer, so please be kind. I would really appriciate any help. It would mean a lot.
